Hisilicon Hi3519A Professional 4K UHD IP Camera SoC H.265

As the next-generation H.265 SoC designed for the 4K UHD IP security cameras and Sport DV cameras, the Hi3519A integrates a new-generation ISP and adopts the latest H.265 compressed video encoder, advanced low-power technology, and low-power design. This SoC is based on ARM® big.LITTLE™ architecture that combined with a powerful ARM Cortex-A17 1.2GHz core and a ARM Cortex-A7 800MHz core. The ARM big.LITTLE processing uses separate cores with different computing powers within the same CPU. The Cortex A17 core, or "big" core, handles intensive tasks like 4K UHD / 2K @30fps video encoding, and the A7 less powerful core executes less intensive tasks like intelligent video analysis.

The Hi3519A supports 90°or 270° rotation and lens distortion correction, which meets requirements in various surveillance applications. It also fully supports 3A algorithms, which allow customers to design different types of IP cameras including the IP AF zoom module. The Hi3519A integrates the POR, RTC, and audio CODEC and supports various sensor levels and clock outputs, which significantly reduces the EBOM costs for the Hi3516A HD IP camera.
